“…Fig.3(d) exhibits values of resistivity taken at 300 K compared to the thicknesses of thin films deposited on different substrates. The observed behavior for different types of substrates (an increase of the values of resistivity with decreasing the thickness of thin films) is quite similar to previously reported results [8][9][10]. However, the LNO/STO heterostructure with thickness of 35 nm exhibits unusually small values of resistivity in comparison with previous observations [15,21].…”

“…Among various oxides, including SrRuO 3 , La 1-x Sr x CoO 3 and LaNiO 3 (LNO) [1][2][3][4] the use of perovskite-type conductive materials as bottom electrodes favors the growth of high quality ferroelectric thin films, such as BTO and PZT [5,6]. From the remarkable family of perovskite oxides, lanthanum nickelate LNO is a rare example characterized by metallic behavior in a wide range of temperatures being at the same time structurally compatible with many active functional layers [7][8][9][10]. LNO has attracted much attention due to its ability to drastically improve the ferroelectric fatigue problem [11,12].…”

We report the structural and transport properties of LaNiO 3 thin films prepared by pulsed laser deposition technique. To understand the effects of film thickness, lattice mismatch and grain size on transport properties, various oriented substrates were used for deposition, including single-crystalline SrLaAlO 4 (001), SrTiO 3 (100) and LaAlO 3 (100). To achieve a high quality LaNiO 3 thin films, the vital parameters (such as laser fluence, substrate temperature, oxygen pressure, and deposition time) were optimized. The best quality films are found to be well textured samples with good crystalline properties.

“…In this paper we present our latest results on magneto-transport properties of C 1−x Co x thin films (with 0.1 < x < 0.2) grown by the Pulsed Laser Deposition (PLD) technique. [26][27][28][29][30][31] Some interesting features in the magnetic field and doping dependences of the measured magnetoresistance have been observed and their origin has been discussed in detail using the up-to-date transport scenarios.…”

We present a comparative study on the influence of applied magnetic field on the resistance of C 1−x Co x thin films (with x = 0.1, 0.15 and 0.2) grown on Si substrate by pulsed laser deposition technique. It is found that the behavior of magnetoresistance (MR) drastically depends on the temperature. Namely, at low temperatures MR is positive and its behavior is governed by the field mediated weak localization scenario. While at high temperatures MR turns negative and its behavior is dominated by electron scattering on ferromagnetic cobalt atoms.

According to the estimates of many authors, in 10-15 years, the world market for nanotechnology products will amount to about 1 trillion $. The share of nanomaterials, in this case, is very large (about 340 billion). Therefore, research on nanomaterials properties becomes one of the most important tasks of the science of nanostructured materials. In this regard, it will be essential to expand research on the influence of size and thermal stability; as two common problems for almost all types of nanomaterials. This review article will discuss the most popular topics on nanomaterials, nanostructures, their history, characteristics and classification as well as status of their scientific articles published in recent years. This study focuses on a range of topics related to the development, research and manufacturing applications of nanomaterials and nanotechnology. There are many problems and challenges that scientists are investigating on them. For example: what are the main differences between the properties of interfaces of nanomaterials (including hybrid ones) from the characteristics of ordinary bulk states? How widely can the self-assembly technique of nanoscale devices elements be developed, considering possible installation errors?
